Adaptors include a smaller
"safety device".
Dampers will not close unless the smaller device is used.

Keep
heat and energy in...rain and animals outIf it's not the cold drafts on your
feet, it's the high energy bills in your mailbox.

You've got a fireplace problem you probably don't know about. It's your damper.
It leaks. Not a lot mind you, but enough to be costing you over $200 a year in
lost energy.

The Lock Top II Damper seals tight with a silicone rubber gasket
That's right, our damper seals with a rubber gasket, not metal to metal like
your current damper. A Lock-Top II Damper seals tight, so virtually no air, and
thus no heat or air conditioning gets lost up your chimney.

The Lock Top II also eliminates downdrafts, seals out rain which can deteriorate
the inside of your chimney, and prevents entry by pests like squirrels,
raccoons, and nesting birds.

The Lock Top II mounts on top of your chimney
On top? Yes, that is the perfect location to create an airtight seal.

A cable drops down your flue and attaches to a handle which mounts where you can
reach it for convenient opening and closing.

Superior stainless steel and cast-aluminum construction equal a lifetime
warranty
The Lock-Top Ii Damper is made of cast-aluminum and stainless steel, precision
fitted with our special silicone rubber gasket. These high-quality materials add
up to a factory lifetime warranty for you.
